Subject [Incubator Wiki] Update of "OpenJPAProposal" by PatrickLinskey
Date Wed, 08 Mar 2006 00:48:11 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The following page has been changed by PatrickLinskey:
http://wiki.apache.org/incubator/OpenJPAProposal

New page:
== Open JPA ==

Patrick Linskey (plinskey at bea dot com) and Eddie O'Neil (ekoneil at
apache dot org)

== Project Proposal ==

Open JPA will be an ASL-licensed implementation of the Java Persistence API
(JPA) which is defined as part of JSR-220.

== Rationale ==

We think that Open JPA is something that will benefit from wide
collaboration, being able to build a community of developers and
committers that outlive the founders, and that will be embraced by other
Apache efforts, such as the Geronimo project as part of an EJB 3.0
container. Given the existing momentum forming behind JPA even at this
early stage, we are confident that an industrial-grade ASL
implementation of JSR220 will attract a diverse community.

== Criteria ==

'''Meritocracy'''

The Open JPA committers recognize the desirability of building software as a
meritocracy and look forward to growing a healthy community of developers to
enhance the JPA APIs.

'''Community'''

The proposed committer community is includes members of the BEA JPA
team and several individuals from the Apache community.

'''Core Developers'''

Fourteen of the initial committers are BEA employees. One of those is a
committer on the Apache JDO project. We anticipate that five of these
fourteen will be involved in the core code development, and the other
nine will be involved in documentation and ongoing QA for the project.

Three of the initial committers are committers on the Geronimo project.
Two are IBM employees involved in the !WebSphere product team. One is
from Intel.

'''Alignment'''

Open JPA will be a candidate for use in Geronimo as the default JPA
implementation. Other projects that have general-purpose JPA needs may be
users of the Open JPA project.

Open JPA has some level of alignment with the Apache DB project. In
particular, the Open JPA codebase already includes support for Derby
databases.

JPA is for use in any Java application, not just J2EE. Therefore, any
application that needs to do data persistence in the object/relational
style (including any application that currently uses Hibernate) will
benefit from Open JPA. 

'''License'''

The existing codebase is owned by BEA and is subject to a proprietary
license. The applicable code will be relicensed under the Apache Software
License 2.0.

== Avoiding the Warning Signs ==

'''Orphaned products'''

Open JPA is a derivative of the basis of the BEA !WebLogic Server (WLS)
EJB3 JPA implementation, and so is an important piece of the BEA code base.

As this is a very eagerly anticipated specification for the Java community,
we expect that this project will continue to grow and develop within its own
community, and be embraced by other open source projects (such as Geronimo)
as well.

'''Inexperience with open source'''

The authors of the existing code (who will be part of the initial committer
list) have experience with open source development already, in both
professional and personal contexts. Examples: serp
(http://serp.sourceforge.net) (used in Kodo currently), sqlline and jline
(http://sqlline.sourceforge.net and http://jline.sourceforge.net) (used by
the Kodo development team, and used by the Apache JDO team), Growl
(http://growl.info).

Four of the initial committers have extensive experience within the
Geronimo project, among other open-source projects.

'''Homogeneous developers'''

The members of the initial committer list have been working in a
distributed, multi-national, asynchronous environment for the last five
years, while working at !SolarMetric. We had a team of up to 7 people working
from 6 different locations over the course of the last five years.

'''Reliance on Salaried Developers'''

Most of the developers are paid by their employer to contribute to this
project, but given the anticipation from the Java community for the a JPA
implementation and the committers' sense of ownership for the code, the
project would continue without issue if no salaried developers contributed
to the project.

'''No ties to other Apache products'''

Open JPA will likely be used by Geronimo, requires some Apache products
(regexp, commons collections, commons lang, commons pool), and supports
Apache commons logging.

'''A fascination with the Apache brand'''

We think that Open JPA is something that will benefit from wide
collaboration, being able to build a community of developers and committers
that outlive the founders, and that will be embraced by other Apache
efforts, such as the Geronimo project.
